Adept was founded in 2004 and consists of musicians Robert Ljung (vocals), Jerry Repo (guitar) Filip Brandelius (bass) and Gabriel Hellmark (drums). In their first year, they released their first demo, Hopeless Illusions, recorded and sold on their own. Their first EP, which was released a year later, was financed out of pocket. The second EP, The Rose Will Decay was released as a proper production. Because of the great success and the rapidly growing awareness of the band, Panic & Action was aware of the group and took them under contract.
